QQ 194535455 Abstract In modern production, jigs and fixtures, as part of the machining tool has e an indispensable technology and equipment. Workpiece production volume is large, in addition to considering the accuracy of the workpiece outside, we also need to take into account productivity and economic issues, so often using special fixtures designed specifically for a particular part of a process designed to make clamping workpieces. Then without scoring and alignment, simply place the workpiece fixture, you can determine the position of the workpiece and the cutting tool and the machine between the clamp and the workpiece. Special fixture is part of a working process of fixture design requirements and manufacturing processes. Its characteristics are highly targeted, not universal. In the relatively stable production, mass production, used a variety of special fixtures, can obtain higher productivity and precision. Dedicated fixture in today's society has been widely used for human development has played a huge contribution. Especially in manufacturing applications, especially in the aerospace, precision instruments, meters, people of
